Gunman's Reward - Brittle and Ashe Book 4

Charlie Brittle and Owen Ashe are accustomed to hunting men for money, but when they are hired to rescue a silver baron’s son from kidnappers they find themselves in over their heads. Followed by a band of outlaws eager to get hold of the ransom money, and partnered with an ex-lawman who seems to know more about the situation than he lets on, Charlie and Owen come to suspect that the only thing waiting for them at the end of this job is their own final reward.
